This error indicates that the system has encountered a situation where a specific number (such as a document number, item number, or other identifier) is expected to be unique, but it has found multiple entries with the same number.
  Causes:
  
  Duplicate Entries: The most common cause is that there are duplicate entries in the database for the number in question. This could happen due to data entry errors, system glitches, or issues during data migration.
  Configuration Issues: Sometimes, the configuration settings for number ranges or document types may not be set up correctly, leading to overlaps.

  Solutions:
  
  Identify Duplicates: Use transaction codes like SE16 or SE11 to check the relevant database table for duplicates. You can run queries to find all entries with the same number.
  Correct Data: Once duplicates are identified, you can either delete or correct the duplicate entries, ensuring that only unique entries remain.

  Adjust Custom Code: If there are custom developments, review the code to ensure it properly handles number generation and uniqueness checks.
  Data Migration Review: If the issue arose after a data migration, review the migration process to ensure that it included checks for duplicates and that the data was cleaned before migration.
